WOVEN W'IRE BED BOT'IOM.

Specification of Letters Patent.

Patented Apr. 18, 19.11.

Application filed January 21, I911. Serial -No. 603,911.

To all whom it may concern:

Be it known that I, Fnnonniox A. PALMER, a citizen of the United States of America, and resident of Middletown, in the county of Middlesex and State of Connecticut,have invented certain new and useful Improvements in VVoveIr'Wire Bed-Bottoms, of which the following is a specification.

This invention relates to certain new and useful improvements in bed bottoms and moreparticularly to that class known as woven wire bed bottoms or mattresses.

One of the principal objections to metallic bedsteads in general use is that the hair or other mattresses which are placed on the woven wire bed bottoms shift laterally on the same-from one side to the other or so spread in use under the weight of the occupant as to present a very unsightly appearance. Various means have been sug gested for overcoming these objections, but so far as I am aware they consist mainly of bent-up longitudinal guards reinforced by heavier strands along the side edges of the mattress and at the upper edges of the guards. These guards are attached to rigid lugs or the like wherebythe guards are held in a substantiallyupright position. This form of guard adds materially to the cost of the mattress and necessitates extraneous devices for supporting the guards while, at the same time, these 'guards'are yieldable outwardly, providinga space into which the edge of the mattress is liable to slide and be held, resulting in injury to the mattress, as well as tending to bind and hold the mattress at one edge, thus keeping the other out of contact with the opposite guard.

It is the main object of the present invention to provide a woven wire bed bottom so constructed as to avoid the above-noted objections and to, at the same time, provide The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part ofthis specification, :and in which- Figure 1 is a perspective view of a woven wire bed bottom constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section on the line 2-2 of Fig. 1. Fig. 3 is a detail in cross section taken as on the line 33 of Fig. 2, looking in the direction of the arrow.

Like numerals of reference indicate like parts throughout the different views.

Referring to the drawings, 1 designates the wovenwire mattress which, in its construction, aside from the novel features here inafter set forth, may be of any of the wellknown forms of woven wire suitable to the purpose. In constructing themattress, I make it somewhat wider than the completed mattress is to be, leaving marginal portions at opposite sides which later are rolled up from opposite edges toward each other, the number of rolls depending upon the desired height of the reinforce of edge. Uponreference to Fig. 3, this roll 2will be best understood. As there shown, the roll consists of four thicknesses of the fabric superimposed upon the body portion proper, making in all five thicknesses. It is evident, however, that the number of thicknesses may be varied without departing from the spirit and object of the invention. The body portion is depressed, as at 3, forming a sort of recess into which the next adjacent recess 4 of the fabric is received. This prevents the hair or other mattress employed upon the woven Wire bed bottom from becoming wedged between the bottom proper and the reinforce of the mattress, especially when the roll is secured as it sometimes is. In Fig. 3 and in Fig. 1 on the right I have shown, as at 5, some suitable means, as for instance a rivet or the like, passed through the different thicknesses at the edge, so as to hold them in close contact. Other means for this purpose may be employed, as for instance a flexible wire or the like 6 which, while holding the folds or different thicknesses substantially in position, allow of a limited movement thereof. A woven wire bed bottom constructed as above described is light, durable, neat in appearance and forms a most efficient sup port for a hair or other mattress, preventing the latter from shifting from side to side and also guarding against the Wedging of the mattress at the edges of the bed bottom.

The Woven wire bed bottom is designed to be secured to the end rails 7 in any suitable manner, these end rails being designed to rest upon the side rails 8 or the bottom may be supported in any other way. In the present instance, I have chosen to show the ends of the mattress as clamped between the vertical portions of the end rails 7 and the plates 9 and firmly held by suitable means, as the rivets or the like 10. It is evident, however, that other means of supporting and securing the bed bottom may be employed.

The rolls at the edges serve to prevent the mattress from getting out of shape, give rigidity to the bottom as a whole and avoid the employment of lugs and vertical guards, together with means for attaching the guards to such lugs.

From the above it will be seen that I have devised a simple and efiicient form of woven wire bed bottom and While the structural embodiment-of the invention as herein disclosed is what I, at the present time, consider prefl erable, it is evident that the same is subject to changes, variations and modifications without departing from the spirit of the invention or sacrificing any of its advantages. I, therefore, do not wish to restrict myself to the particular construction and arrangement of parts as hereinbefore disclosed, but reserve the right to make such changes, variations and modifications as come properly within the scope of the protection prayed.

The application of weight to the wire bed bottom deepens the recess for the hair or other mattress in proportion to the weight applied, aifording more protection against lateral sliding of the mattress; the greater the weight, the higher, the more tense and more efiicient the rolled edge.

What is claimed as new is 1. A woven wire bed bottom or mattress having at its side edges integral reinforcing rolls each composed of a plurality of thicknesses of the fabric and means for holding said rolls in compact form.

2. A woven wire bed bottom or mattress having at its side edges rolls composed of a plurality of thicknesses of .the fabric, the lowermost thickness of the roll being received Within a depressed portion of the body proper of the mattress.

8. A woven wire bed bottom or mattress.

having at its side edges rolls composed of a plurality of thicknesses of the fabric, the lowermost thickness of the roll being received within a depressed portion of the body proper of the mattress, and means passed vertically through the thicknesses of the rolls for holding them in compressed compact form.

Signed by me at New York, N. Y., this 19th day of January.
